Most people might consider standing alone on the platform late in the evening waiting who knows how long for the next train to arrive a somewhat boring experience, to say the least.
However, for someone like myself, I consider it a unique opportunity to look around and enjoy how interesting things might have turned out to be otherwise.
Not that I believe that certain events might have been different or that I might have decided to conduct a number of actions separately rather than grouped into the same temporal unit.
That is not the point.
The point is that one chooses according to how events proceed well before one really knows how these events will proceed.
Ideally it should be a balanced mixture of grouped and separated actions, if of course such a compromise were ever possible.
